Converting Category 3/4 Convertible Quick Coupler Upper Hook

CAUTION: Use proper lifting device when converting coupler. Failure to do so can result in personal injury.

NOTE: A second person is recommended to align components during conversion.

When full power is to be used on 8320R and 8345R tractors with ground engaging implements it is recommended to use CAT 4 upper hook if implement set up allows. The CAT 3 upper hook may be overloaded with very high draft loads.

1. Support quick coupler frame (A).

A second SMV emblem must be mounted on the quick coupler mounting bracket provided and must be used when quick coupler is in raised position or implements are mounted on the quick coupler.

   When not in use, place the second SMV emblem in storage location on the right hand side of transmission.
